ATTACHMENT FOR OIL-CLOTH MACHINES.

Appfication filed November 4, 1913.

1 b all whom it may concern Be it known that I, EcInIUs WVrnsER, a subject of the Emperor of Austria-Hungary, residing at Passaic, in the county of Passaic and State of New Jersey, have invented new and useful Improvements in Attachments for Oil-Cloth Machines, of which th following is a specification.

The general object of the invention is to refine certain steps in the process of manufacturing oil cloth, linoleum and the like. And to these ends the invention resides in substituting mechanically operated doctorboards in lieu of the manually operated derices heretofore employed for preventing the liquid coating, upon its being applied to the textile base, from flowing over the sides of the base.

Other objects will appear and be better understood from that embodiment of my invention of which the following is a specification, reference being had'to the accompanying drawings forming part hereof, in which v Figure 1 is a detail contracted front elevation of my invention showing the positions the parts thereof will normally occupy when the invention is in use. Fig. 2 is a detail contracted side elevation partly in section but showing the components of one side on a larger scale than in Fig. 1. Fig. 3 is a detail in side elevation of the part in the lower portion of Fig. 2 but look ing at that face of the board opposite from that shown in the said figure. 'Fig. 4 is a horizontal section on the line l4 of Fig. 3. Fig. 5 is a detail showing the means for locking the hanger in elevated position.

My device is intended for use with all types of machines employed for manufacturing oil cloth or linoleum. It is intended to operate at a part of the machine located adjacent to the point where the coating of oily material is applied to the fabric.

As is well-known the fabric prior toreceiving on one of its surfaces the oily' coat ing, is rolled on a suitable spindle which supports the fabric and admits of its being fed to the apparatus which supplies the oily coating. From this point the coated fabric is directed to the other parts of the machine which operate in the usual manner on the oily coating.

In adapting amachine for making oil cloth for use with my invention, I provide the said machine (not shown) with suitable Specification of Letters Patent.

hangers (not shown) and to these hangers I attach a cross bar 5, which cross bar, as will be observed by referring to Fig. 1, is arranged horizontally and located considerably above the path which the fabric 6 follows upon passing from the roll to the mechanism which applies the oily coating. The cross bar 5 supports at its opposite ends a pair of horizontally disposed sleeves 7. 8 which function as pivots for eyes 88' and the eyes 88 are suitably connected to hangers ac. The said hangers aa are extensible as to length and each consists -=of an outer tubular section 9 which receives an inner section 10, suitable pin and slot structures 11 being associatedwith the sections 9 and 10 and operating to limit the sliding movement of the inner section 10 in the outer sections 9.

The hangers a-a normally depend vertically downward and are disposed on opposite sides of the path which the fabric 6 follows after the application of the coating of oily material thereto and adjacent to the ends of the knife or leveler (not shown).

12-12 indicate the doctor-boards. These elements are of suitable shape, dimensions and material,- whereby to adapt them to bear on the edges of the strip 6 and the ends of the knife for the purpose of preventing the oily coating from flowing over that edge of the strip upon-being operated upon or leveled by the knife.

As shown in Figs. 1 to 4 inclusive, each board. 12 is provided at its lower portion with suitable means for connecting the strip 6 with the board as the strip upon being coated, passes to the other parts of the machine. In the present instance, each of such guides is shown in the form of a pair of jaws 1313 between which the strip is directed and by which it is retained against sagging or upward bulging or such other movement as would operate to disconnect it from the boards. Between the guides on each board 12 the strip 6 is additionally held and especially against lateral movement independently of the board by a plurality of suitable devices, such as star wheels 14: whose points, as the Wheel rotates, pass successively into the path of the strip 6 and consequently successively embed themselves in the said strip. As shown in Fig. a each of such wheels-is provided with a shaft 15 which is journaled in a bearing These sleeves are provided with spindles 16 suitably mounted on the board 12, such bearing herein shown to be in the form of tubular boxing 16 arranged in an opening in the board and having at one end a cross piece 17 which is connected to the board by screws 18 or their equivalents.

The type of board thus far described is intended for use in connection with machines in which the leveler or scraping knife is arranged vertically. However, in machines where the knife or scraper is arranged obliquely extensions 12 are provided. As shown in Figs. 2 and 3 these extensions are formed of sector-shaped pieces of metal pivotally connected as indicated by 18 to the lower rear corners of the boards. The upper portions of these extensions are provided with slots 14 through which pass set screws 15 which function to secure the extensions in any of their adjusted positions. Obviously with this construction, the extensions may be adjusted to correspond to the obliquity of the knife or leveler and when so adjusted and brought to bear upon the oppo- Q site end portions of the knife, will effectively prevent the material from flowing over the sides of the body.

19 are angular-shaped brackets which are connected at one end to the boards 12 by suitable fastening means, such as bolt-s 20. The opposite ends of these brackets are connected to adjustable connecting rods 21 whose upper ends are adapted to loosely receive the spindles 8 as shown in Figs. 1 and 2.

Now inasmuch as the roll of fabric to be coated with the oily material, is invariably wound unevenly, it follows that perceptible. lateral movement of the strip of fabric will be had between the roll and the boards 12- 12 as the strip moves from the roll to the machine, therefore, and since-the strip after the application thereto of the oily coating must be kept in the horizontal in order to insure against the running of the coating to one side of the strip in the event of the tilting of the same, I effect a connection between the brackets and hangers and connecting rods which will insure against the boards tilting the strip 6 when the said strip is moved laterally in either direction by reason of the uneven winding as previously mentioned. In the present instance, this connection is shown to be effected by pivot pins 22 which pass through the brackets 19 and the lower ends of the inner sections 10 and by pivot pins 23 which pass through the brackets 19 .and the lower ends of the connecting rods 21. Now by virtue of the construction of the hangers a and the pivotal connections between the brackets 19 and the hangers and connecting rods, any lateral lVhen it is found desirable to remove the boards from their normal positions as will be necessary when adjusting the strip of textile material onto the machine, provision is made for holding the several parts heretofore described in an elevated position so as to not interfere with the movements of the operator. In the present instance the sleeves 7 are provided with spring-pressed latches 7 When the hangers a a are. in their normal positions as shown in Figs. 1 and 2, the engaging ends of these latches abut the faces of the eyes 8, whereby the latches are held retracted. When either standard is swung upwardly and outwardly from the position shown in Figs. 1 and occupies a position at substantially right angles to that shown the latch 7 will come into alinement with an opening 9 shown in Fig. 5 and upon passing into this opening under the action of this spring 10 will efiectively hold the hanger in elevated position. Each latch is provided with a handle 11 which forms a convenient hand-hold for retracting the latch when it is desired to lower the standard.

What is claimed as new is:

1. Apparatus for preventing the flowing of oily substances over the sides of the strip of fabric to which said substance is applied in a machine for making oil cloth, comprising a support, and a plurality of vertically disposed boards arranged for bearing on the opposite sides of the fabric strip and pivotally connected to the said support.

2. Apparatus for preventing the flowing of oily substance over the sides of the strip of fabric to which said substance is applied in a machine for making oil cloth, comprising a support, and a plurality of counter balanced boards arranged for bearing on the opposite sides of the fabric strip and pivotally connected to the said support.

In testimony whereof I affix my signature in presence of two witnesses.
